style: use single quotes everywhere and add a rule to eslint

[CptSchnitz]

Which problem is this PR solving?

• use single quotes everywhere and add a rule to eslint #582

Short description of the changes

• Added ESlint rule for single quote
• Ran ESlint:fix on the entire repo
• Went over the README's and changed to single quotes there
• fixed single quotes in scripts

(There's also eslint.config.js itself, but I wasn't sure if everywhere includes it, tell me if I should also edit it)

So it failed the test because of a package that came out a few minutes ago (@babel/parser):

that's interesting 😅

It's probably just bad timing. @babel/core was published, the dependency was not.
Trigger new CI run with an empty commit git commit --allow-empty.

i've restarted the build myself but you should be able to do it if you go on the build page (by clicking on either tasks) and click on "Restart all jobs" on something like this at the top right

When i look at my own repos, i have a button that says "re-run jobs",
but it doesn't show up here.
